As for the original question, why would Nothing be displayed as 0 unless the column contained numbers, in which case an empty string is obviously no help because it's not a number. It sounds to me like the user should be using a collection instead of an array, so that items can be genuinely removed and not just "cleared".
I have to use an array because it is a part of the assignment. The button allows the user to delete items from the array. The problem is that Nothing still holds a place in the array. I want to get rid of it entirely.
